In this March 14, 2006 file photo, a herd of wild horses grazes near the Carson River in Carson City, Nev. About 33,000 wild horses roam in 10 Western states, about half of those in Nevada. The horses and burros are managed by the Bureau of Land Management and protected under a 1971 law enacted by Congress. (AP Photo/Nevada Appeal, Chad Lundquist)
